Abstract: Stomatal guard cells play important roles in plant development by controlling water and CO2 exchange between the plant and the environment. The repeatable movements of stomata depend on the characteristics of guard cell wall. Biochemical and molecular studies with the help of computational modeling have greatly increased the understanding of the specific roles of guard cell wall components and characteristics on stomatal function. We summerized the recent advances on the essential roles of polarized wall of guard cell on the stomatal function, and the deposition process and evolutionary conservation of the polarized wall. Meanwhile, the latest finding of the specific influence of cell wall components on stomatal movement were also summarized, particularly in the fields of molecular genetics and biochemistry. We also proposed the future research on the molecular mechanism by which guard cell wall is involved in the function of stomata, which was aimed to provide new insight for genetic engineering of guard cell wall.
